The Pixel Farm has released version two of PFTrack, its 3D tracking environment. PFTrack 2.0 is available now and will be demonstrated at Siggraph next month.

PFTrack’s optical flow tools track individual pixels from one frame to the next, building a data model of all pixel movement within a sequence. This data can then be used as a single reference point by Pixel Farm plug-ins within applications such as Apple’s Shake and Eyeon’s Digital Fusion.

The company claims that PFTrack 2.0 includes more advanced optical flow functionality, now allowing users to analyse per pixel inter-frame motion, as well as improved Matte editing functionality and a new option to export to Adobe After Effects.

The Pixel Farm also claims that the enhanced tracking and calibration core gives increased speed, in comparison to V1.5, extending the range of shots that can be tracked. Improvements have also been made to the image manipulation algorithms speeding up the process of cleaning up footage prior to tracking.

Other optical flow analysis improvements include a new calculation algorithm, proxy resolution flow field support, brush-based flow editing tools, matte and feature-based flow control and export to floating-point and RGB images.

An open API has been designed to allow third parties to access PFTrack’s data model. The accompanying release of the optical flow application plug-ins provides the same interface found when applied to plate stitching, retiming, motion blur and layer extraction that is currently found with PFStable and PFBarrel.

PFTrack 2.0 is available for £3,000 plus VAT for a full commercial license and £50 plus VAT for a student or academic licence. Upgrades from previous versions are available for £300 plus VAT.
